The state Department of Environmental Management says staff members will tag maple and ash trees at risk of being infested by the Asian longhorned beetle and emerald ash borer.

The yellow and orange tags will identify the tree species, which pest to look for and DEM contact information.

The tagging begins Monday in various locations in Newport. It will continue Tuesday along Blackstone Boulevard and at Fargnoli Park in Providence; at Lincoln Woods State Park in Lincoln; and at Goddard Memorial State Park in Warwick.

Officials say early detection of the pests is key to getting rid of them.
